Extreme brain fart: which number is larger?

Members do not see this ad.

1.6x10^-9 or 6.1x10^-9.

Embarrassing as hell, but I can't tell which is larger. I want to say the second one, but lol, I forget.

Second one

write out decimal form. easier to see that way.

Nice. Because I was thinking, that's close to 10 x 10^-9, which is 1x10^-8, which is larger. Cool. I'm on pg 195 of TBR GChem.

im tired of mcat studying. its no fun : (

I've been burned out and pressure is on for me to return back to the medical world 2 days after this test. I'm studying about ****ing molar solubility and this is what my PA friend is asking me in the ICU:

question
a fib patient
got 1 gram of magnesiums sulfate
iv
why?
they dont have v fib
just a fib
no torsades
magnesium levels are normal
am i right to be confused by this?
do they ever give it prophylactically?​

could it be given for SOB?

Also:
Ksp AgCl = 2x10^-10; Ksp PbCl2 = 2.0x10^-5
I think I understand why AgCl is least soluble, but I get an answer of around 1.4x10^-5, is that right?

AgCl
http://www.wolframalpha.com/input/?i=x^2+=+2*10^-10 least soluble molar solubility = 1.4 x 10^-5

PbCl2
http://www.wolframalpha.com/input/?i=4x^3+=+2.0x10^-5 most soluble molar solubility = 1.7 x10^-2
